I love the Apricot PC/Xi. They're very British; technically and aesthetically brilliant, ahead of their time, unreliable and incompatible. They run a variant on MS-DOS but aren't PC compatible. They have a proprietary 800x400 monochrome display. This might help:

The PC video connector pinout is:
Pin Description
1 +12v out
2 no connection
3 0v
4 horizontal sync
5 vertical sync
6 frame ground
7 no connection
8 ground (signal ground?)
9 video signal
This is the same as the Xi (I ran the same monitors on both at one
time), but I am not sure if the F1 is the same.
Text below table in tech. ref. manual:
"Both sync signals are at standard positive TTL levels. The frequency
of the Horizontal Sync pulses to match the standard 9 inch Display Unit
is 15.79 kHz; the frequency of the Vertical Sync Pulses, 72 Hz. The
amplitude of the video signal is fixed at 0.3V for normal intensity
video, 0.4V for high intensity. The maximum current allowed to be drawn
from the +12V suipply is 1.0A."
